Critics of the atomic phase-out said energy emissions, costs and imports would all rise. They were wrong.

With the UK taking another step towards supporting new nuclear power on Tuesday – at either no extra cost to the consumer if you believe ministers, or substantial cost if you believe most others – it's worth taking a look at what actually happens when you phase out nuclear power in a large, industrial nation.

In this scenario, an ambitious energy efficiency program along with massive development of renewable energy happen in parallel, so that by 2050, the global energy system is 95% powered by renewable energy. Energy will move towards a decentralised system using local renewable sources such as wind, solar and geothermal.

zerocarbonbritain2030 is a positive, realistic vision for an energy progressive society free from fossil fuels. It provides political, economic and technological solutions to the urgent challenges raised by climate science. It explores the synergies between sectors to create the first fully integrated solution to climate change.

Renewables and energy saving can deliver more carbon savings than nuclear

Neil Crumpton, until recently Friends of the Earth’s anti-nuclear campaigner/energy spec­ialist, has produced a “carbon-negative” non-nuclear UK 2050 energy scenario. The proposed infrastructure would have the potential to go beyond low-car­bon energy technologies should climate protection policies re­quire it. Neil will soon be em­ployed by the Bellona Founda­tion to set up a Bellona UK to progress such far-reaching energy and climate solutions.

The Stop Nuclear Power Network is a UK-based non-hierarchical grassroots network of groups and individuals taking action against nuclear power and its expansion and supporting sustainable alternatives. We encourage and seek to facilitate nonviolent direct action, as well as more conventional forms of campaigning.
